Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Dice the potato into 1/2-inch cubes and toss them in a bowl with half of the olive oil, half of the sea salt, half of the black pepper, and all of the smoked paprika.
Spread the potatoes in a single layer on the baking sheet and roast for 20-25 minutes until they are golden and crispy.
While the potatoes roast, heat the remaining olive oil in a large skillet over medium-high heat.
Add the shrimp to the skillet and cook for 2-3 minutes per side until they are pink, opaque, and cooked through.
Stir in the minced garlic and lemon zest, sautéing for about 1 minute until the garlic is fragrant but not browned.
Season the shrimp with the remaining sea salt and black pepper, then remove the skillet from the heat.
Drizzle the lemon juice over the shrimp and toss with freshly chopped parsley.
Plate the succulent garlic shrimp alongside the crispy roasted potatoes and serve immediately.
